Abstract

Wave overtopping of coastal structures depicts a hazard for community, property, and infrastructure within the vicinity of low land areas. Given the growing threat of climate-change-induced floods, the wave attacks, particularly in Kelantan low-lying areas, can substantially affect the occurrence of wave overtopping at various coastal structures. Hence, a precise prediction of wave overtopping for different coastal structures is essential to protect community and property nearby the coastal structure areas. Smoothed Particle Hydrodynamics (SPH) method using DualSPHysics was conducted to simulate wave overtopping on flow thickness, velocity, and volume discharge. Understanding the complexity of beach dynamics and hydrodynamic characteristics were assessed using Profiler 3.2 XL and MIKE-21 to determine the current beach morphology with existing coastal structures and gain better insights into the dynamic visualization of wave overtopping. The result shows that the variation of the beach morphology throughout the storm event greatly influences the wave flow and velocity, while the wave overtopping discharges are influenced mainly by the defending of coastal structures to impede the wave overtopping water drains discharge inland. This study demonstrates the most desirable choices concerning the effectiveness of coastal structures design and types are profound in coastal erosion and flood management purposes visually and realistically.
